Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has a plurality of planting claws that are pivotally supported on a planting case that is rotationally driven around a horizontal axis, thereby controlling the rotation of the planting case. The present invention relates to a seedling planting device for a rice transplanter configured to take out seedlings one after another from a seedling take-out port of a seedling stand and plant them while each planting claw maintains substantially the same posture.

[Conventional technology]

There is a desire to improve work efficiency in rice transplanting work, and one example of a structure that embodies this desire is Utility Model No. 60-5531.
It is disclosed in Publication No. 7. This structure is a model that speeds up the planting process by using multiple planting claws to plant one row, instead of planting one row with one planting claw like normal models. .

[Problem that the invention seeks to solve]

In the above-mentioned structure, the planting claw takes out the seedlings at a higher speed than the conventional model and plunges into the mud surface to plant them, so the surface layer and mud are likely to adhere to the tip of the planting claw. If there is foreign matter such as surface layer or mud attached to the tip of the planting nail, it may not be possible to take out the seedling with the tip of the toe when passing through the seedling take-out port, and even if you can take out the seedling, it will not work properly. There are cases where the seedlings are taken out in a tilted position and planted in this tilted position, rather than in the (ψ) position.

The present invention focuses on the above-mentioned points and aims to provide a relatively simple structure that can keep the tip of a planted nail clean at all times.

[Means for solving problems]

The feature of the present invention is that in the seedling planting device of the rice transplanter mentioned above,
As the planting case rotates, a scraping member is provided on the back of each planting claw that comes into contact with the tips of other planting claws to scrape off mud, etc., and its functions and effects are as follows. It is.

[For production]

In a type in which each of the plurality of planting claws rotates while maintaining approximately the same posture, as shown in Fig. 5, the toe of one planting claw (3B) is rotated while the planting case (2) is rotating. Planted nails (3A
) always exists at least once. Therefore, at this time, the scraping member (17) provided on the back surface of the planting nail (3A) comes into contact with the toe of the planting nail (3B) behind it, and scrapes and removes foreign matter from the toe.

This scraping action is performed continuously at all times while the planting case is rotating.

〔Effect of the invention〕

As described above, by using the rotation of the planting case, it is possible to always keep the toe of the planting nail free of foreign matter, thereby minimizing the possibility of poor planting of the planting nail due to the attachment of foreign matter. Now you can.

〔Example〕

Hereinafter, an embodiment of the present invention will be explained based on the drawings. Fig. 1 shows a seedling planting device (A) and an agricultural granular material feeding device (
As shown in the figure, the planting case (2) is rotatably supported around the horizontal axis (P, ) at the rear end of the planting mission (1). With,
Two sets of planting claws (3A) at both ends of the planting case (2),
(3B), and two sets of planting claws (3A) as the planting case (2) rotates.

(3B) is configured so that seedlings are alternately cut out from the seedling outlet (4a) of the seedling stand (4) and planted in the field. A float (5) for leveling the ground and maintaining its posture is provided at the bottom of the seedling planting device (1).
A) is connected via a link mechanism (6) to a wheeled traveling body (not shown) so that it can move up and down.

On the other hand, as shown in the figure, the fertilizer applicator (B) includes a tank (7) for storing fertilizer or seed rice and a feed roll (not shown) that intermittently feeds out the powder and granules in the tank (7). It consists of an internal feeding section (8), and the planting mission (
1) It is installed on top.

The powder and granules coming out of this feeding part (8) are transferred to a hose (9).
From there, it is fed into a trench made in the field by a trencher (10).

The groove creator (10) and hose (9) are shown in FIGS. 1 and 3.
As shown in the figure, the planting nails (3A) and (3B) pass! It is placed on the side of the planting mission (1) from the lL trace, and the groove JS (10) is attached to the float (5) via the groove cutting plate (18), and the area near the lower end of the hose (9) is placed on the side of the planting mission (1). It is supported by a substantially U-shaped support member (20) extending from the lower surface of the support rail (19) of the platform (4). Further, the support member (20) may be formed into a substantially U-shape as shown in FIG. 4.

Next, the structure of the planting case (2) will be explained in detail.
As shown in Figures 1 and 2, planting mission (1)
The drive shaft (11) protrudes left and right from the planting case (2).
is fixed to this drive shaft (11), and a cylindrical fixed shaft (13) fixed to the planting mission (1) is fitted onto the drive shaft (11), and the planting case (2 ), and the fixed shaft (1) is inserted into the planting case (2).
A first gear (14) is fixed to 3).

On the other hand, there are planting claws (3A) on both ends of the planting cage (2).

(3B) is pivotably supported, and its pivot shaft (1
The gear part (15a) of 5) meshes with the first gear (14) via the second gear (16), and the swing shaft (11
), the planting case (2) is driven to rotate, and both planting cases (=J claws (3A), (3B) are placed in the seedling take-out port (4a) in the posture shown in Figure 1 by the aforementioned gear engagement action.
After 13 days, the seedlings are taken out and planted in the field.

Then, as shown in FIGS. 1 and 2, the fertilization device (
The feeding section (8) of r() is equipped with a swing arm-type feeding drive section (8a) that reciprocates an internal feeding roll, and this feeding section (8a) and the planting claw (
3A) and the shaft end of the swing shaft (15) are interlocked and connected via a link (12).

Then, as shown in the same figure, both planted nails (3A), (3
B) A scraping member (1
7) is attached, and as the planting case (2) rotates, one planting claw (3B) is attached as shown in Figures 2 and 5.
) when the tip of the toe passes behind the other planted nail (3A),
The scraping member (17) comes into contact with the toe of the planted nail (3B) and scrapes off the surface layer, mud, etc. adhering to the toe. This effect is the same when the toe of the planted nail (38) passes behind the other planted nail (3B).

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
